Be it 'known that I, HENRY OMEARA, a

citizen of the United States,

t I residing at Sioux Falls, in the county of Minnehaha and State ofSouth Dakota, have invented certain new and useful Improvements inAcetylene-Gas Generators, andI do declare thefollowing to be'a full,clear, and exactdescriptioii of the invention, such' as will enableothers skilled in the art to which ap'pertains to make and u'se thesame.

This invention relates to improvements in acetylene gas'generators andthe primaryobject of the inventionis to'provide a simply constructedgenerator of, theherein debed character,'w hich will be eflicient andreliable in operation.

A 'secondary object is td' provide simple H and eificientmeanspoperatedby the descent of the gasbell; for openingthe valve in th e carbidhopper, thereby allowing 'a new charge of carbid; to enter thegeneratingchamber.

v i Still another: obj is tofprovide structure wherebythe tube whichconducts the carbid from the hopper'f't'o the generating 1 hopper beingclosed. Figitis adetailhorizontal section on the line 4,430f Fig. 5;

Inthe I accompanying drawings, "I have shown improved generator ascomprising, inf general, a water-tank 1, a gas bell 2, a carbid- 'hopper"3 and various "connections for controlling the feedr'of the carbid andfor alsoreceivingthe gas generated.

The water is preferably cylindrical andis open at its upper end, whileits lower end isclosed by asolid bottom 4:. Spaced a suitabledistancefromy said bottom &' is a horizontal partition 5' having its Jcentral portion bulged upwardly as at 6 HENRY oMEARA Ol-l SIOUX FALLS,SOUTH DAKOTA.

and in communication with the interior of an upright pipe 7. This pipe 7has atWofold function y of conveying carbid to the "spacebetween thebottom 4: and thepa rtition 5 and of conducting the gas generated insaid space to the house connection or serv- 93 P P a As clearly shown inthe drawings, the bell'2 is of cylindrical contour and is provided witha solid top 8, while its lower end is entirely open as is common withdevices of this character. The top 8 ofthe bell is provided with acentral opening 9 within which a sleeve 10 is rigidly secured, saidsleeve surrounding the pipe 7 and having its lower end flared outwardlyas at 11. Thus it will beseenthat thepipe acts also as in its ascent anda guide for thebe ll 2 descent. The top 8 of the bell 2 is also providedwith an eccentric opening 12 from whicha small cylinder 13 rises, saidcylin der'being closedat its upper end and provided with a suitableIoopor eye 14:, the function of which will hereinafter appear.

In addition to the hereinbefore set forth uses of the pipe Tyit alsoforms a rigid supportfor the carbid hopper 3., Said hopper comprises afunnel shaped lowerjend 15 which is in communication withfthe interiorof the pipe 7 and is provided with an upright, wall 16 at its upperedge. The

upper edge of the wall 16 is provided with a cover 17, the latter havinga threaded filling opening 18 which'is normally'closed by a screwcap'19. Vithin the hopperB and disposed in vertical alinement with thepipe -7, is a substantially cylindrical guide 20 which,"as shown,is'c'losed at itsupper end while itslower end is entirely open and isspaced from the junction of the'lower end 15 of the hopper 3, withtheZpipeTI. The

guide 20 may be rigidly secured in this ;po

sitlon' in any suitable manner, a sleeve 21,

leading from said guide 20 through thle wall 16, usually answering thispurpose. The

outer end of the sleeve 21 is externally threaded and engaged withinternal threads in a boss 22,formed on the outer side of the wall '16,said outer end of the tubebeing provided with anannular'collar 21 whichcontacts with the inner side of said wall. As clearly seen in Fig. 3,the boss 22 receives, in its outer end, a packing nut 22 betweenwhichiand the'adjacentend of the tube, 21;a

packingring is located,the adjacent ends of said tube and said nut beingcountersunk to force said packing ring into engagement with a shaft 23which is located in said tube and is provided on its-inner and outerends with crank arms,2at and respectively, said arms pro ect1ng inopposite dlrectlons from said shaft. The crank arm 24 is looselyconnected, through the instrumentality of a plurality of links 26, tothe upper endof a weighted valve 27, said valve being coneshaped at itslower end as shown at 28, said As seen in Fig. 3, the guide 20 is formedwith a laterally extending boss 20 through which the inner end of thetube 21 prOJects into the interior of said guide, a nut 20 beingthreaded on said inner end thus clamping the boss 20 securely betweensaid nut and a second annular collar 21 which is formed on the inner endportion of the sleeve 21. By this arrangement of parts, it will be seenthat the guide 20 is rigidly supported within the hopper and that theouter end of the tube 2l acts asvone member ofa stuffing box.

hen the valve 27 is seated, the crank arm 25 will extend upwardly atsubstantially an angle of 45 and the gas hell 2 will be supported by thepressure of the generated gas as will be hereinafter described. As thegas is exhausted from the interior of the bell, and said bell graduallydescends, it becomes expedient to provide means for automaticallyraising the valve 27, thereby allowing the, fresh 7, charge of carbid todescend through thepipe 7 and into the generating chamber betweenthebottom 4: of the tank I, and the partition 5 therein. For thispurpose I employa chain 29 or other suitable connection, between theouter end of the arm 25, and the loop or eye 14. Thus it will readily beseen, that when the bell 2 de scends, said chain will pull downwardlyupon the arm' 25, this movement rocking the shaft 23 and through theaction of the crank arm2l and the links 26, raising the valve 27 toallowa charge of carbid to drop into thejpipe By reference to Fig. 1, itWill beseenthat the only outlet from the generatingfchamber, is the pipe7 andtherefore allgas' generated in said chamber must neccssarily risewithin said pipe. For the purpose of conducting the generated gas fromthe interior of the pipe 7, to the house connection and to the interiorof the bell 2,.I provide a horizontal pipe 30 which extends outwardlyfromthe pipe 7 and passes through the upright wall of the tank 1, itsouter end being'in communication with a filter 31, the latter having asuitable nipple 32 to which the service pipe is connected. Intermediateits ends, the pipe 30 is'provided with an outwardly opening check valve33 and with a valve 34: which -.may be employed for. cutting off theflow of gas entirely, or for conducting it to any one of the number ofdischarge pipes (not shown). The pipe 30 is provided, between the checkvalve 33 and its outer end, with a depending pipe 35 which hasits lowerend turned inwardly as at 36, beneath the lower end of the hell 2 andrises as at 37,, its u pperiend discharging into the cylinder :13carried by the topof the'bell 2, i v v 'With the parts asabovedescribed, the op;

bid hopper 3 is filled with carbid and the shaft 23 is rocked in such amanner as to cause the valve 27 to rise within the guide fromsaid-burners. The major pa ft of the gas generated will,' however,descend through the pipe 35 and willhtherefore be discharged in theupper end of the gas bell 2, said bell being substantially filled withwaterl from the tank l. The gas within the hell; 2 will now caus'e'saidbell to rise and will-thus re lease all" tensionon the chain} 2 9. Theweighted valve 27 will now drop'by gravity to automatically check the,des'centof the carbid and consequently no more generation said bell hasbeen exhausted and again descends/ a i .H

By the provision of the outwardly opening check valve 33, itwill be seenthat'the gas to the generating chamber through the pipes 35,30and7. i

For the purpose ofremovingthe exhausted carbid or sludge, from 'thegenerating chamber, I provide a valvedpipe 4:0 which communicates withasuitable suction pinnp and with the interior of said. generatingchamber. The suction through thepipeAO, although removing the major partof said sludge, would not be sufficiently strong to reach all parts ofsaid chamber. Irther efore 20 and thereby allow a quantityofsaid.cara

throughsaid service pipe and be discharged 7 from the hell 2 isprevented from'returning eration of the device is as follows: The carioowill take place until-some of the gaswithin iio provide an agitatingfinger or rod 41 which lies iiponthe bottom 4 and is provided with anupright operating rod 42 which ,passes revolubly through a tube i3,within the tank 7 1 and hasits upper endtnrned laterally; as

,1 44: toprovide a suitable operating handle.

By the provision of this agitating means, the sludgeupon said bottom: 4,maybe read- -'ily loosened andtherefore thesuction within the pipe 40will be sufficient to remove the 3 same.

From the foregoing description, taken in f connection with theaccompanying draw- ,lngs, the construction and operatlonof the inventionwill be readily understood without requiring a more extendedexplanation. Various changes in form, proportion and 'minor details maybe resorted to without do a parting from the spirit of the invention'asclaimed, 1 r
